ISO 898-1 property class 8.8 quenched-and-tempered carbon steel slotted cheese head machine screws manufactured to DIN 84 / ISO 1207.

Applications & Selection Guide
ISO 898-1 property class 8.8 slotted cheese head machine screws to DIN 84 / ISO 1207. Quenched and tempered, 800 MPa nominal, broad cylindrical head with a straight slot. Listed M3–M10. The slot limits tightening torque compared with an internal-hex cap screw.
Specify class 8.8 cheese head screws for higher-strength covers, fixtures, and equipment housings that still want a slotted cylindrical head. The slot limits tightening torque compared with an internal hex — for high clamp in a compact head, DIN 912 is the better drive. Mate with class 8 nuts if nutted.
